FlLLlNG-REPLENISHING LOOIVI.

SPECIFICATION forming part of Letters Patent No. 766,151, dated. July 26, 1904.

Apnlication filed May II 1904. Serial No. 207,438. (No model.)

To (Ml whom, it may concern.-

Be it known that I, ALIDA M. MARooUX, a citizen of the United States, and a resident of Hopedale, county of \Vorcester, State of Massachusetts, have invented an Improvement in Automatic FillingReplenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings re presenting like parts.

In automatic looms of the Northrop type (see United States Patent No. 529,9ei0) the running filling is replenished from time to time by automatically inserting a fresh fillingcarrier into the running shuttle, and thereby causing the ejection of the more or less exhausted filling-carrier from the shuttle, the ejected filling-carrier dropping into a suitable receptacle.

Means have been provided (see United States Patents Nos. 6l1,763 and 677,096) to part the old filling end between the edge of the cloth and the shuttle when filling replenishment is effected, the ejected filling-carrier as it drops acting to pull the parted and trailing filling end out of the shuttle-eye to clear the same and prevent fouling of the fresh filling and also to prevent the parted end from being carried back by the shuttle into the cloth. Sometimes this fouling would occur, and it was found in practice that if a tall box or receptacle was provided for the ejected fillingcarriers the parted filling" end would pull over the upper edge of the receptacle as the lay receded after replenishment and materially aid in clearing the shuttle-eye of the old filling. In actual practice, however, there are some objections attendant upon the use of such tall receptacles, their tops reaching very close to the lay when forward. For instance, if the weaver inserted his hands into the receptacle to remove a filling-carrier his knuckles were apt to be struck and injured by the lay, owing to the small clearance-space, yet with 'a low receptacle, which was free from this trouble, the old filling end would at times be left in the shuttle-eye after replenishment.

My present invention has for its object the production of means whereby in an automatic loom of the character specified the parted filling end is engaged and caught between the shuttle and the ejected filling-carrier, so that as the lay recedes after filling replenishment the parted filling end will be effectually drawn out of the shuttle-eye.

By my invention fouling of the shuttle and the fresh fillingis obviated, the old filling end cannot be drawn into the cloth, and a receptacle for the spent filling-carriers or bobbins may be made of such height that there will be nointerferenceif the weaver wishes to remove any of the filling-carriers therefrom.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a partial front elevation of the replenishing side of an automatic loom of the type referred to with one embodiment of my invention applied thereto, only a portion of the filling-feeder being shown. Fig. 2 is a transverse sectional detail thereof on the line 2 2, Fig. 1, showing the replenishing mechanism and the novel features embodying my present invention in normal position; and Fig. 3 is a detail similar to Fig. 2., but showing the transferring devices ready to operate to effect filling replenishment and with the device for catching the old filling end in readiness to act.

The filling-feeder F to hold the reserve filling-carriers Z), the transferrerf", mounted to rock on the horizontal stud f and to remove the filling-carriers one by one from the feeder to the shuttle S, (which latter is of the automatically-self-th reading type, the controlling rock-shaft (.Z, and the lay A, cut away at A below the shuttle-box 13 at the replenishing side of the loom, said shuttle-box being slotted in its bottom at 10, Fig. 2, to permit the discharge of a filling-carrier ejected from the shuttle at the time of filling replenishment, are and may be of well-known construction and operation and require no further detailed description.

Suitable means are provided for rotating the filling-feeder intermittingly and form no part of my present invention.

The downturned end f of the transferrer has a rotatable spring-controlled stud m thereon, on which is mounted an arm m having an attached notched dog m to cooperate with the bunter C on the lay when filling replenishment is to be effected, the arm m having a lateral lug m thereon to be engaged by a branch 3 of a pivotally-mounted yoke, all substantially as in United States Patent No. 641,792, hereinbefore referred to. As in said patent the other branch y of the yoke (see Fig. 2) forms a shuttle-feeler and is provided with means (indicated at P) to part the old filling end between the cloth and the shuttle when replenishment takes place; but any other similar thread-parting means may be used, so far as my present invention is concerned.

It will be understood that when the rockshaft (1 is turned in the direction of arrow 100, Fig. 2, the yoke yy will rock rearwardly, and thereby the parting means P will be positioned, and at the same time the spring 8 turns the stud m to. place the dog m in the path of the hunter 0 as shown in Fig. 3, and the transferrer will be operated as the lay heats up into dotted-line position, Fig. 2.

In the present embodiment of my invention the outer end of the transferrer-stud f is extended and has secured to it by a set-screw 1 the hub 2 of a downturned arm 3, the arm, as shown in the drawings, being bent or shaped to bring its lower end to a point below the path of movement of the shuttle-race and opposite the cut-away part A of the lay. Said arm 3 is provided at its lower end with a tubular or sleeve-like bearing 4, provided with a longitudinal slot 5 to receive a pin 6, (see Figs. 2 and 3,) projecting laterally from a carrier (shown as an elongated rod 7) slidably mounted in the bearing 4 and at right angles to the breast-beam.

The carrier at its outer end is reduced in diameter at 8, and a spring 9 is coiled around saidreduced portion between the outer end of the bearing 4 and the shoulder 40 on the carrier, the pin 6 preventing any rotative movement of the carrier, while permitting it to slide in the bearing.

At the front end of the part 8 is secured a lateral arm 11, held in place by asuitable setscrew 12 and having an upturned end 13, (best shown in Fig. 1,) adapted to cooperate with a depending and outwardly-turned finger 14, secured by a set-screw 15 on the extended end of the stud m. r

The finger and the cooperating upturned part 13 of the arm 11 are shown in dotted lines in Fig. 2 in their normal position. At such time the finger acts through the arm to retract the carrier 7 against the expansive action of the spring 9 in the position illustrated in Fig. 2, and at such time when the lay beats up the back wall 10 of the cut-away part of the lay will not hit the said carrier or the attached filling end or thread-catcher, to

be hereinafter described. When, however, filling replenishment is to be effected, the stud m is turned in the direction of the arrow 90,

Fig. 2, to elevate the notched dog m into the elongated bar or rod 16, rigidly secured to the a rear end of the carrier 7, as by a screw 17, (see dotted lines, Fig. 2,) the catcher having its front face roughened or notched, as at 16 Fig. 1. When the carrier 7 is released, as has been described, and the lay heats up, the thread-catcher 16, which is inturned and in parallelism with the wall 1O on the lay, will assume a position beneath the replenishing shuttle-box B and behind the path of the filling-carrier, to be ejected at the time of filling replenishment.

The change of filling inserts a fresh filling into the shuttle, and the filling-carrier previously held in the shuttle is ejected through the bottom of the replenishing shuttle-box and is discharged to any suitable receptacle below the loom, and as the ejected filling-carrier drops the filling end which has been parted by the parting device P will pass in front of the catcher 16, such parted filling end leading from the ejected filling-carrier to the shuttle. Now as the lay recedes after filling replenishment has been efiected the shuttlebox will of course be moved away from the thread-catcher, and thereby the filling end will be engaged and caught by the catcher, and as the lay moves back the engaged filling end will be pulled out of the shuttle-eye to clear the same. If for any reason the backward movement of the lay should be IDSUfiI'. cient for this purpose, it will be manifest that the first shot of the shuttle from the replenishing-box will cause a clearance of the shuttle-eye. will be completed by or through the action of the thread-catcher 16 upon the backward movement of the lay.

The roughening or notching of the front face of the catcher insures the engagement of the same with the filling end.

In Fig. 2 I have shown by a broken line 20 the path of the filling end when the lay has swung back after filling replenishment, it being supposed that all the parts have returned to their normal position after replenishment.

ITO

Ordinarily, however, the clearance I prefer to mount the carrier in a spring-controlled or yielding manner, substantially as hereinhefore described, as the thread-catcher is thereby enabled to impinge against the wall 10 of the lay beneath the replenishing shuttle-box when replenishment is to be effected; but it will be manifest that the spring control of the carrier is not absolutely necessary, for I may rigidly mount the carrier so that the tln-ead-catcher will just escape engagement with the lay when the latter is at front center.

The various parts of the thread-catching device are adjustable, as may be necessary or desirable, by means of the set-screw hereinbefore referred to, and it will be observed that the only change in the main construction of the loom to apply my invention thereto consists in elongating the transferrer-stud f and the rocking stud In.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be modified and rearranged in various particulars by those skilled in the art without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a loom in combination, automatic filling-replenishing mechanism, means to part the old filling between the cloth and shuttle upon filling replenishment, and means mounted on the loom to engage the parted filling end between the shuttle and the ejected filling-carrier and cause such filling end to be drawn out of and clear the shuttle-eye.

2. In a loom provided with automatic filling-replenishing mechanism, and with means to part the old filling between the cloth and shuttle upon filling replenishment, the combination of means to clear the shuttle-eye of the parted filling end, said means includinga thread-catcher positioned below the shuttle during filling replenishment and behind the path of the ejected filling-carrier, to engage the parted filling end between the shuttle and the filling-carrier from which it leads.

3. In a loom provided with automatic filling-replenishing mechanism, and with means to part the old filling between the cloth and shuttle upon filling replenishment, the combination of means to engage the parted filling end between the shuttle and the ejected filling-carrier and cause such filling end to be drawn out of and clear the shuttle-eye, said means including a fixed support, and an elongated thread-catcher mounted thereon and adapted to pull the parted filling end out of the shuttle-eye as the shuttle moves away from replenishing position.

4. In a loom provided with automatic filling-replenishing mechanism, and with means to part the old filling between the cloth and shuttle upon filling replenishment, the combination with a lay having a replenishing shuttle-box through which the ejected filling-carrier is discharged, of a device adapted to extend longitudinally beneath said shuttle-box during filling replenishment and behind the path of the ejected filling-carrier, to catch the parted filling end leading therefrom to the shuttle and pull it out of the shuttle-eye as the lay moves back after replenishment.

5. In a loom provided with automatic filling-replenishing mechanism, and with means to part the old filling between the cloth and shuttle upon filling replenishment, a lay having a shuttle-box slotted to permit the discharge of an ejected filling-carrier, a fixed support, a spring controlled carrier mounted thereon and rearwardly extended, a device to normally retain the carrier retracted, and an elongated thread-catcher rigidly mounted on the rear end of the carrier and extended longitudinally below the path of the shuttle-box, the operation of the filling-replenishing mechanism effecting release of the carrier to permit it to engage the lay below the slotted shuttle-box and behind the path of an ejected filling-carrier, to cause the thread-catcher to engage the parted filling end between its fillingcarrier and the shuttle-eye and thereby draw the filling end out of the eye as the lay recedes after filling replenishment.
